Dimensionless time for interference testing in homogeneous reservoirs - Earlougher
Input(s)
k: Permeability (mD)
\(\emptyset\): Porosity (fraction)
\(\mathrm{t}\): Time \((\mathrm{h})\)
\(\mathrm{k}\): Overall Production \((\mathrm{mD})\)
\(\mu\): Viscosity \((\mathrm{cP})\)
\(c_{t}\): Total Compressibility \((1 / p s i)\)
\(\mathrm{r}_{\mathrm{w}}\): Wellbore Radius (ft)
Output(s)
\(t_{D}\): Dimensionless Time (dimensionless)
Formula(s)
\[
\mathrm{t}_{\mathrm{D}}=\frac{0.0002637 * \mathrm{k} * \mathrm{t}}{\emptyset * \mathrm{c}_{\mathrm{t}} * \mu *\left(\mathrm{r}_{\mathrm{w}}^{2}\right)}
\]
